Notes:
   ^a  γ₂ = mass concentration of ferric hydroxide
   ^b  S = concentration of gas in liquid phase/concentration of gas in gaseous phase

Method/Apparatus/Procedure:
   Volumetric static method. Care was taken to reduce dead space because of the small amounts of gas absorbed. Apparatus similar to that described in Ref. 1.

Source and Purity of Materials:
   (1) No details given.
   (2) prepared by method of Noyes (Ref. 2).
   (3) Nothing specified

Estimated Errors:
   Solubility: δS = ± 1 % (estimated by compiler)
   Temperature: δT/K = ± 0.1(estimated by compiler)
